Is there a problem adding "Tracking" options when creating a campaign?

[toddryks01]

I get a System.NullReferenceException error whenever I try adding any of the 3 tracking options. All of the other options work fine:

MailChimpManager mc = new MailChimpManager(mcAPIkey);
CampaignCreateContent content = new CampaignCreateContent();
content.HTML = (mailHeader + mailContent + mailBottom);
CampaignCreateOptions options = new CampaignCreateOptions();
options.Title = campaignName;
options.ListId = mcListId;
options.ToName = "*|FNAME|*";
options.FromEmail = "xxx@zzz.com";
options.FromName = mailFromName;
options.Subject = mailSubject;
options.Authenticate = false;
options.AutoFooter = true;
options.InlineCSS = true;
options.GenerateText = true;
options.Tracking.TextClicks = true;
